same sire were similarly affected; of the dam, one; in the latter 
:ase the dam’s sire had a spavin, thus making the history of he¬ 
redity in this case interesting. 
The age of development in one case is not given ; in one dur¬ 
ing the fourth month (this animal is now a weanling and spavin 
is well developed), in one at ten months, one at one year, two at 
two years, three at four years (the sire of one of these was per¬ 
fectly sound, but possessed a bad formation of hock; his colts in- 
heredited this formation, and many were known to be spavined in 
breaking); three developed at five years old, two at six years 
(one of these had a rather badly formed hock, but stayed sound 
doing very heavy work till six years old, then threw out a spavin 
while at pasture ; # he is now seven years old); one developed it at 
seven years, and one at eleven years old ; this has been repeatedly 
blistered and fired, but the animal is still lame. 
In four cases, breed was not given, eight were grade Normans, 
two were thoroughbreds, one grade Belgium and one roadster. 
Of the eleven ringbones, seven were males and four females; 
in color four were bays, two each brown, sorrel and iron grey, 
md one dun ; in four, breed is not given ; four were grade per- 
:herons, one pony, one Hambletonian and one standard bred. In 
:wo the age of development is not given ; in two, it developed at 
;ix years, in one at twenty-five months, and one each at the ages 
}f three, five, nine, eleven, fourteen and sixteen years. 
In five cases the sires and dams were sound, in four not 
known ; in one both sire and dam were similarly afflicted; the 
only case where grandparents could be traced was in the case 
ff standard fillies, and both were free from ringbone. In one 
case the subject transmitted it to two of her colts. 
Of those afflicted with specific ophthalmia, one was a stallion, 
our were geldings and six were females ; in color four were bays, 
;wo each greys, sorrels and chestnuts, and one brown; in breed 
iight were grade Normans, three trotting, and one grade draft. 
The age of development varied from the ninth month to the 
eighth year, but seemed most common between the ages of two 
ind four years. 
In four cases both sires and dams were sound, in two cases
